1 Claim.

This invention appertains to new and useful improvements blades of ice skates.

The principal object of the present invention is to provide a skate sharpener which will properly hold the blade of a skate during the operation of sharpening the same.

Another important object of the invention is to provide a sharpening apparatus for sharpening skates which will be more satisfactory in use than the present marketed type of sharpening means now on the market.

Still another object of the invention is to provide an apparatus which will permit an ice skate to be sharpened lengthwise instead of crosswise thus eliminating the small ridges remaining 'on the runner as a result of the crosswise method of sharpening.

Other objects and advantages of'the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents an end elevational view of the apparatus.

Figure 2 is a top plan view.

Figure'3 is a side elevational view.

Figure 4 isa fragmentary detailed sectional view on line 44 of Figure 2.

Figure 5 is a sectional view on line 5-5 of Figure 3.

Figure 6 is a fragmentary detailed sectional view through the adjusting means.

Referring to the drawings wherein like nu-,

merals designate like parts, it can be seen that numeral 5 represents-the base on which is the motor 6. Extending upwardly from one end of the base 5 is the elevated platform or stool 1 from which rises the pair of upstanding shells 8 and 9, through the upper portions of which extends the shaft Ill, one end of which is provided with the sharpening wheel II.

Numeral l2 represents a post which is formed with a slot I3 in its lower portion through which the screws I4M are disposed and driven into the formation I5 on one side of the stool I. Obviously by loosening and tightening these screws the post I2 can be adjusted vertically.

The upper portion of the post I2 is suitably secured to one end of the table It which is provided with the reduced extension H at one end upon which the clamp block I8 is mounted. The clamp block I8 is formed with transversely extending slots I 9 through which the screws 2!! are disposed, these screws being disposed downwardly into the extension I1. Obviously, the block I8 can be adjusted inwardly or outwardly with respect to the shoulder M and against which in means for sharpening the shoulder the blade of an ice skate can be clamped in the proper adjusted position.

A reduced neck portion 22 is formed between the extension proper H and the shoulder El and has the opening 23 therethrough into which extends the peripheral portion of the grinding Wheel II.

Upwardly extending ribs 24 are provided on this neck portion 22 to serve as rests for the blade of the skate being sharpened.

A bolt 25 having its headportion svvivelly disposed as at 26 through the top of the table I6 has its lower threaded portion 21 threadedly disposed into the upper portion of the shell 9. Thus when the post I2 is to be adjusted, the bolt 25 can be adjusted accordingly in fixing the desired elevation of the table.

The shaft II! can be adjusted longitudinally and held by the tapered end of the screw 28 engaging into the V-shaped circumferential groove 29 of the shaft I0. I

The armature shaft 30. of the motor 6 drives the belt 3| which in turn is trained over the pulley 32 on the shaft I0.

Obviously with apparatus of the above construction a skate can be conveniently and efficiently sharpened by lengthwise application of the operating means, thus eliminating the ridges which occur as result of crosswise sharpening. Furthermore either thin or thick bladed skates can be sharpened with equal ease and a proper hollow ground effect obtained for either by simply changing the abrading element.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention what is claimed as new is: v v

A skate sharpener comprising a base, a table, vertical adjusting means between the table and the base, a grinder, said grinder being operative through the table, said table being constructed to provide a shoulder, a clamp block on the table adjustably mounted in opposed relation to the said shoulder, and between which and the shoulder a skate blade can be clamped, and a skate centering rib rising from the table in close proximity to the said shoulder, said table being formed with an opening through which the grinder is operative, said opening being in alignment with the rib and interrupting the rib at the intermediate portion thereof.
